WENDELL PHILLIPS ANTHONY, OF RIDLEY PARK, PENNSYLVANIA, ASSIGNOR TOWILLIAM P. SIMPSON, OF PHILADELPHIA, PENN- SYLVANIA.

LAWN-NIOWER;

SPECIFICATION forming part of Letters Patent No. 762,975, dated June 21,1904-..

Application filed August l, 1902.

4To nfl?, wil/0111, t nea/y concern:

Be it known that I, WENDELL PHILLirs AN- THONY, a citizen of the UnitedStates, residing at Ridley Park, in the county of Delaware and State ofPennsylvania, have invented certain new and useful Improvements in Lawn-Mowers, of which the following is a'specifcation.

My invention relates to improvementsf in lawn-mowers, and moreespecially to that class of mowers intending to be used in connectionwith automatic means of operation-"such, vfor instance, as is shown in`Letters Patent to Mr. W. P; Simpson, No. 706,864; and my inventionconsists of means for regulating the action of the cutters, as fully setforth herewith and as illustrated in the accompanying drawings.

Figure 1 is a side view of the mower embodying my invention, the cap ofthe gearcasing and gears being removed. Fig. 2 is a plan view, Fig. 3 isa rear elevation. Fig. 4 is a section on the line 4 4, Eig. 3. Fig. 5illustrates the driving-roller frame and adjusting device. Fig. 6 is anenlarged horizontal section of the part of the driving means, showingthe automatic clutch device.

Fig. 7 is a view looking in the direction of the\\ arrow, Fig. 6, and atthe sides of the beveled y, bearings 5 to illustrate their relativepositions;

The frame B may be the frame of a mower or of acornbined mower androller. As shown, it is the swivel-frame of an automatic roller ormowcr-such, for instance,as is now well known--and as the other parts ofthe construction do not pertain to my invention they are not shown.

The frame B, whatever its character, is provided with what I term thedriving-roller D, as this roller is the means of driving the cuttingdevices, which, as shown, consists of a rotary cutter E and a fixedcutter or knife E. The cutting devices are carried on a frame C, soconnected to frame B that the cutter can be raised from the ground whenit is not desired to mow. As shown, the frame C swings about the axis ofthe roller I), the shaft 6 of sem-.1110. 117,999. (No model.)

which turns in the bearings of the frame B, with intermediate gearingsbetween theshaft 6 and the shaft of the rotary cutter E. This gearingmay be of any suitable character. As shown, a sprocket-wheel 2 turnsaround the shaft 6 and is connected, through a chain 3, with a sprocket4, fixed on the shaft of the rotary cutter.

It is desirable to arrest the rotation for the operation of the cuttingdevices when elevated, and I therefore provide means, which may be ofany suitable character, for disconnecting the driving-gear when thecutters are elevated. As shown, there is a twopart clutch L, havingannular ratchets the parts of which may be thrown into and out ofengagement automatically as the frame C is lowered or raised. One clutchpart, 12, is on the sprocket 2. The other, 13, turns with and slides onthe shaft 6. A plate 14 fits an annular groove in the part 13 and slideson two pins 9 9. on the frame C, and this plate 14 carries pins 10 10,

the ends of which make contact with reversed bevel-faces of bearings 5 5on the frame B when the cutter E is lowered, and these bevelfaces forceoutward the plate 14 and clutchsection 13 and bring the two parts of theclutch into engagement. When the cutter is raised, springs 8 8 carry theclutch-section 13 inward, and the Adriving-roller 'will not operate thecutters.

It is desirable to adjust the cutter to different heights to determinethe height of the cut. For this purpose I provide bearings on one of theframes and an adjustable bearing or contact-piece on the other. Thusthere is a lug 15 on frame B, Fig. 5, and a shaft 16 extends through theframe C and carries an eccentric 17, (shown in Eig. 5 and in dottedlines, Fig. 1,) which when cutters are'lowered contacts with the lug,and by turning the shaft 16 the shaft to be set and secured in differentpositions.

In the construction shown the frame B is supported at the rear byswivel-rollers J J, and the gearings are in a casing in the frame C,closed by a detachable cap 20.

Without limiting myself to the construction shown, 1 claim- 1. Alawn-mower provided with a drivingfoller, a frame supported to swingabout the axis of the driving-roller, cutting devices carried by saidswinging frame, means for driving the cutting devices from the roller,anddevices whereby said means are disconnected on carrying the cuttingdevices out of working position, substantially as set forth.

2. A lawn-mower provided with a drivingroller, 'a frame supported toswing about the axis of the driving-roller, cutting devices carried bysaid swinging frame, and driving means, including a clutch, to connectthe cutting devices and the roller only when the cutting devices are inworking position, substantially as set forth.

3. The combination with the driving-roller of a lawn-mower, of a framecarrying the cutters in position forward of the drivingroller and'pivoted to permit the cutters to be raised and lowered, drivingconnections between the roller and cutters, and means whereby saiddriving connections are disengaged automatically on elevating the frame,substantially as described.

4. The combination with the driving-roller, frame carrying the rotarycutter swinging about the axis thereof, a gear turning freely about saidaxis and connected to turn with the cutter, and provided with aclutch-section, a second clutch-section connected to turn with thedriving-rollerk and sliding to and from the other section, and means forautomatically carrying the sections outof engagement when the cutter iselevated, substantially as set forth.

5^. The combination of a frame carrying a driving roller and shaft,cutter -carrying frame, gears between the driving-roller and cutter, anda two-part clutch, one part connected with one of the gears, and theother turning with and sliding on the roller-shaft, springs arranged toseparate the parts of the clutch,-and bearings on the roller-frame andon the sliding part of the clutch to carry the latterl into engagementwhen the cutter is lowered, substantially as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WENDELL PHILLIlS ANTHONY.
